Abstract

Automated analysis of ultrasound data is provided to extract event times, such as valve opening and closing times. Different types of ultrasound data, such as B-mode, M-mode, tissue velocity or flow velocity, are processed by a processor to identify automatically the event times. The event times are used for the processing of ultrasound data or to assist diagnosis. The event times may be used to estimate other event times in different heart cycles, such as with interpolation or extrapolation.
